Specification of Letters Patent.

Patented July 16,1912.

Application filed March 30, 1912. Serial No. 687,315.

To all whom it may concern:

Be it known that I, BERTRAM N. Soon, a citizen, of the United States of America, residing at Detroit, in thecount-y of Wayne and State of Michigan, have invented certain new and useful Improvements in Proof- Pr esses, of which the following is a specification, reference being had therein to the accompanying drawings.

In the publication ofnewspapers it is desirable that the proofsof type matter and illustrations be taken as rapidly as possible after being set, and this is a matter of some difficulty where such displays exceed the capacity of single galleys.

This invention relates to a proof press adapted to quickly take proofs from a form of any size up to full pages without'the removal of same from the make-up table and without the aid of skilled'labor, the press being arranged to be used in connection with a plurality of make-up tables.

The invention consists in the matters hereinafter set forth .and more particularly pointed out in the appended claims.

' In the drawings, Figure 1 is a view in vertical longitudinal section through a make-up table and press that embody features of the invention, showing the press in the position assumed in taking an impression; Fig. 2 is a view in end elevation of a press; Fig. 3 is a plan view thereof; and Fig. 4 is a view in detail showing the position assumed by the press for. the withdrawal of the proof sheet.

7 Asherein shown in preferred form a floor plate 1, with beveled front edge 2, supports uprights 3 that are suitably interconnected by braces 4 to form a rigid structure carrying a pair of parallel side plates 5. A pair of studs 6 on the innerface of each of the side plates engage oblique slots 7 in track bars 8. An eccentric cam plate 9 j-ournaled in one of the side plates on a suitable stud 10 may be swung by a handle 11; to slide one of the plates 5 rearwardly and upwardly on its studsfi, A rock bar 12 journaled across the rear end portions of the sides 5, has a pairof depending rock arms 13 each entering a transverse slot shown at 14 in the track bars so that upward movement of one by manipulation of the lever 11 carries the other track bar with it in exact parallel relation. A roller 15 travels on the track bars, and has a padded central portion 16 with the usual covering for this class of work. The roller may be conveniently moved along the track bars by a handle 17. A cross brace 18 between the front ends of the sides 5 has cushion stops 19 arranged to arrest the roller, the rearward movement of the roller being defined by collars 20 on the rock bar 12. The cross braces 4 are so disposed as to leavethe space between the front posts of the structure clear and this with the beveled edge 2, permits a make-up table with chase 21 thereon to be rolled into position between the track bars. The make-up table is so disposed that the top thereof is in substantially the plane of the track bars so that when the chase is placed on the table, the roller clears the top face of the chase when the track bars are in raised position and rests upon it when the track bars are in lowered position as indicated in Fig. 1.

The chase 21 is filled with the form while on the make-up table and when proof is required the form and chase are run into the press, inked, and a proof sheet placed thereon. The roller is then brought over the chase and lowered thereon by dropping the track bars. The roller is then passed over the sheet making a clear impression after which it may be raised for withdrawal of the make-up table.

The chief advantage of this construction lies in the fact that large sized chases may be placed upon't-he make-up table, the typematter and illustrations inserted and a print taken therefrom without moving them from the make-up table. Such removal from the make -up table which is necessary where proof is taken upon an ordinary press requires great care to prevent the type matter from dropping out .and with large sized or full page chases this is very difficult. 'The arrangement of the press for the reception of the make-up table with chase thereon eliminates this difficulty and enables the operator without looking up the form to take the proof as readily as from a single galley.

Obviously changes in the details of construction may be made without departing from the spirit of the invention and Ido not care to limit myself to any particular form or arrangement of parts.

What I claim' is 1. The combination with a make-up table, of a floor plate on to which the make-up table may be rolled, roller trackways sup ported on the floor plate at substantially. the level of the make-up table, a pressure roller traveling on the ways, and means forelevating and lowering the trackways to raise and depress the roller above the surface of the make-up table.

2. The combination with a make-up table and a, chase supported thereon, of a floor plate on to which the make-up table may be rolled, roller trackways secured on the floor plate in substantially the plane of the chase, a pressure roller traveling on the trackways over the chase, and means for elevating and lowering the trackways to raise and depress the roller above the chase, the roller being adapted to travel on the chase when the trackways are depressed.

3. The combination with a make-up table, of a floor plate on to which the make-up tablemay be rolled, a pair of side plates secured on the floor plate in substantially the plane of the bed of the make-up table, a pair of parallel track bars movably'supportedon the side plates, apressure roller traveling on the track bar s, andmeans for simultaneously lowering the' track bars to allow the roller to rest on the surface of the type or matter contained in the chase.

4. The combination witha make-up table, of a floor plate adapted to receive and support the make-up table and chase thereon,.

side plates supported in parallel relation on the floor plate in substantially the plane of the surface of the chase, a pair, of parallel track bars adjustably mounted 'on the side plates, means for simultaneously raising and lowering the track bars, and'a pressure roller on the track bars adaptedto have rolling contact With the contents of the chase on the make-uptable when the track barsare depressed.

5. The combination with a make-up table, of a pair of side plates, means for supporting the side plates in substantially the plane of the surface of the chase on the make-up table, adapted to allow the make-up table to be moved between the plates, a pair of guide studs on the inner face of each side plate, a pair of track bars each having obliquely disposed guide slots engaged by the studs, an oscillating member for moving one of the track bars of the studs, a rock bar in unison, a chase on the make-up table, and

a pressure roller traveling on the track bars when the latter are elevated and on the chase when they are depressed.

6. The combination with a make-up table and chase thereon, of a pair of side plates,-

means for supporting the side plates at substantially the plane of the chase on the make-up table, adapted to allow the makeup table to be moved between the plates, a pair of guide studs on the inner face of each side plate, a pair of track bars each having obliquely disposed guide slots engaged by the'studs, an oscillating member for moving one of the track bars on the tuds, a rock bar journaled' across the side plates, rock arms on the bar engaging the track bars to move in unison, a chase on the make-up table, and stops for limiting the movement of the roller onthe track bars.

7. The combination of a floor plate, an upright structure thereon adapted to receive a make-up table when the latter is rolled on to the plate, "a pair of parallel side plates supported on the structure in substantially the horizontal plane of the chase on an inserted make-up table, a pair of studs on the inner face of each side plate, a pair of track bars each provided with a pair of obliquely disposed guide slots engaged by the studs ofa companion side plate, a cam journaled on one side plate bearing against the end face of the companion track bar, a rock bar journaled across the side plates and provided with rock arms engaging the track bars to,

move them together, a pressure rollertraveling on the track bars, a' make-up table adapted to be rolled into the structure on the floor plate between the side plates, and a chase on the make-up table adapted to receive the roller when the track bars are depressed. 7 V
